Detail Display for Object Hierarchy with Children?

robc

I found a couple old discussions about using the object hierarchy to organize books and pages, or books and chapters. I'm using CA 1.7.15 with the dacs-heritage profile and the default theme with a few tweaks.

Is there no display of child objects in the default theme?

I've been using collections instead of parent objects so that I can navigate the thumbnails of all the objects in Pawtucket. This has some pros and cons, so I'm wondering if it's easy or a major project to get child object thumbnails to show up in the parent object details so that I can navigate an object hierarchy as easily as my collections?

Hello,
I am developing a print catalogue raisonné and I am using a parent-children relation for prints and states. The object view looks like this
http://www.lestampemoderne.org/CA_AB/pawtucket/index.php/Detail/objects/15
The ca_objects_default_html.php file has this section for the children 🇦 {{{
<div class="child_record"> 
<unit relativeTo="ca_objects.children" sort="ca_objects.preferred_labels" sortDirection="desc" delimiter="</br>">
<div class="title">
<l>^ca_objects.preferred_labels.name</l>
</div>
etc...
</unit>
</div> 
}}}
Is it what you are looking for ?
All the best,
Etienne

I'm hoping to get a search-style display similar to the way objects are displayed within collections.

I think I figured out something just now. When I was reading the _access_points list in the indexing file, I noticed this works to find what I need...

/Search/objects/search/children:1234

... which displays the objects who have parent id #1234.

It worked! I just tested my idea by opening ca_collections_default_html.php and copying the whole block for displaying objects.

I pasted the block into ca_objects_default_html.php and only needed 2 changes.

I changed ifcount code="ca_objects" to ifcount code="ca_objects.children".

Then for the indexing access point I changed 'search' => 'collection_id:^ca_collections.collection_id' to 'search' => "children:$vn_id".

All that's left to do is make an easy-to-use link pointing back to the parent object detail page.

@ebarthel I like the idea of having a custom template for the children. I will consider something like that in the future.

Thanks for sharing the solution. I'll try it out as well. Could turn out useful for me too...
